| Description | Single band (SDS-PAGE). Streptavidin is a biotin-binding protein found in the culture broth of the bacterium Streptomyces avidinii. Like its namesake avidin, streptavidin binds 4 moles of biotin per mole of protein with a high affinity virtually unmatched in nature (Kd~10-15). Streptavidin lacks carbohydrate side chains present on avidin and has an isoelectric point nearer to neutrality where most useful biological interactions occur (pI of 5-6 vs 10 for avidin). As a result, streptavidin frequently exhibits lower levels of non-specific binding than does avidin when the proteins are used in applications relying upon the formation of avidin/biotin complexes (Chaiet and Wolf, 1964). In ELISA-based diagnostic systems, antibodies directed against a particular antigen may be covalently attached to reporter enzymes. Antigens are then quantitated by enzymatic assay after binding to these conjugated molecules. The precise conditions for accomplishing such covalent attachments must be determine |
